1375429 - [e10s] Regression: No focus events fired on menu items in pull down menus off the main menu bar

Status: RESOLVED FIXED

(Core :: Disability Access APIs, defect)

Description

[Marco Zehe (:MarcoZ)]

This is a regression introduced in the first of the 2017-06-21 nightly builds, and was not resolved by whatever it was that triggered the second nightly. I mentioned it in the meeting on Wednesday that I no longer get speech from menus. Using Nightly and NVDA:

1. Press Alt to open the menu bar.
2. Press DownArrow to pop into the File menu.

Expected: You should hear the New Tab menu item spoken. And sometimes, this does happen. But often, this is already where the bug reproduces. If you hear it, just continue to press DownArrow.

Actual: The menu items are not spoken. But they are there in the tree, so it is the focus events that are missing.

The 2017-06-20 build was still OK. No other settings have changed between the two builds from my end.

Attachment: Properly handle popup accessibles

Popups don't pass the IsRoot check, but we still need to return them. In that case, we should just use the regular Accessible::GetNativeInterface machinery.
